Abstract
This brief proposes an output voltage-tracking controller for dc/dc boost converters, ensuring the target closed-loop performance recovery property. The proposed method is designed via a multivariable approach, not a cascade method, accounting for the nonlinearity in the converter dynamics and plant-model mismatches. A nonlinear observer is constructed to exponentially identify the disturbances caused by the plant-model mismatches without using the true parameters of the converter. The resulting observer acts to recover the target closed-loop performance by estimating and canceling the disturbances, besides removing steady-state errors. Simulations and experiments are performed to verify the effectiveness of the proposed method by using a 3-kW dc/dc boost converter.
